18 This is the control program of tinc, a secure virtual private network (VPN)
23 to alter and inspect the running VPN's state.

26 .It Fl n, -net Ns = Ns Ar NETNAME
27 Communicate with tincd(8) connected with
29 .It Fl -pidfile Ns = Ns Ar FILENAME
32 to authenticate with a running tinc daemon.
33 If unspecified, the default is
34 .Pa @localstatedir@/run/tinc. Ns Ar NETNAME Ns Pa .pid.
36 Display short list of options.
38 Output version information and exit.
40 .Sh ENVIRONMENT VARIABLES
41 .Bl -tag -width indent
43 If no netname is specified on the command line with the
45 option, the value of this environment variable is used.

51 Create initial configuration files and RSA and ECDSA keypairs with default length.
54 for this node is given, it will be asked for.
55 .It config Oo get Oc Ar variable
56 Print the current value of configuration variable
58 If more than one variable with the same name exists,
59 the value of each of them will be printed on a separate line.
60 .It config Oo set Oc Ar variable Ar value
61 Set configuration variable
65 All previously existing configuration variables with the same name are removed.
66 To set a variable for a specific host, use the notation
67 .Ar host Ns Li . Ns Ar variable .
68 .It config add Ar variable Ar value
69 As above, but without removing any previously existing configuration variables.
70 .It config del Ar variable Op Ar value
71 Remove configuration variables with the same name and
75 is given, all configuration variables with the same name will be removed.
77 Start an editor for the given configuration file.
78 You do not need to specify the full path to the file.
80 Export the host configuration file of the local node to standard output.
82 Export all host configuration files to standard output.
83 .It import Op Fl -force
84 Import host configuration file(s) from standard input.
85 Already existing host configuration files are not overwritten unless the option
88 .It start Op tincd options
91 optionally with the given extra options.
99 Partially rereads configuration files. Connections to hosts whose host
100 config files are removed are closed. New outgoing connections specified
105 Shows the PID of the currently running

108 Generate both RSA and ECDSA keypairs (see below) and exit.
109 .It generate-ecdsa-keys
110 Generate public/private ECDSA keypair and exit.
111 .It generate-rsa-keys Op bits
112 Generate public/private RSA keypair and exit.
115 is omitted, the default length will be 2048 bits.
116 When saving keys to existing files, tinc will not delete the old keys;
117 you have to remove them manually.
120 Dump a list of all known nodes in the VPN.
122 Dump a list of all known connections in the VPN.
124 Dump a list of all known subnets in the VPN.
126 Dump a list of all meta connections with ourself.
127 .It dump graph | digraph
128 Dump a graph of the VPN in
131 Nodes are colored according to their reachability:
132 red nodes are unreachable, orange nodes are indirectly reachable, green nodes are directly reachable.
133 Black nodes are either directly or indirectly reachable, but direct reachability has not been tried yet.
134 .It info Ar node | subnet | address
135 Show information about a particular node, subnet or address.
136 If an address is given, any matching subnet will be shown.
138 Purges all information remembered about unreachable nodes.
143 Capture log messages from a running tinc daemon.
144 An optional debug level can be given that will be applied only for log messages sent to
149 to try to connect to all uplinks immediately.
152 attempts to do this itself,
153 but increases the time it waits between the attempts each time it failed,
156 didn't succeed to connect to an uplink the first time after it started,
157 it defaults to the maximum time of 15 minutes.
158 .It disconnect Ar NODE
159 Closes the meta connection with the given
164 is compiled with libcurses support, this will display live traffic statistics
165 for all the known nodes, similar to the UNIX
168 See below for more information.
170 Dump VPN traffic going through the local tinc node in
172 format to standard output,
173 from where it can be redirected to a file or piped through a program that can parse it directly,
178 Examples of some commands:
179 .Bd -literal -offset indent
180 tincctl -n vpn dump graph | circo -Txlib
181 tincctl -n vpn pcap | tcpdump -r -
185 Example of configuring tinc using
187 .Bd -literal -offset indent
188 tincctl -n vpn init foo
189 tincctl -n vpn config Subnet 192.168.1.0/24
190 tincctl -n vpn config bar.Address bar.example.com
191 tincctl -n vpn config ConnectTo bar
192 tincctl -n vpn export | gpg --clearsign | mail -s "My config" vpnmaster@example.com
194 The top command connects to a running tinc daemon and repeatedly queries its per-node traffic counters.
195 It displays a list of all the known nodes in the left-most column,
196 and the amount of bytes and packets read from and sent to each node in the other columns.
197 By default, the information is updated every second.
198 The behaviour of the top command can be changed using the following keys:
201 Change the interval between updates.
204 key, enter the desired interval in seconds, followed by enter.
205 Fractional seconds are honored.
206 Intervals lower than 0.1 seconds are not allowed.
208 Toggle between displaying current traffic rates (in packets and bytes per second)
209 and cummulative traffic (total packets and bytes since the tinc daemon started).
211 Sort the list of nodes by name.
213 Sort the list of nodes by incoming amount of bytes.
215 Sort the list of nodes by incoming amount of packets.
217 Sort the list of nodes by outgoing amount of bytes.
219 Sort the list of nodes by outgoing amount of packets.
221 Sort the list of nodes by sum of incoming and outgoing amount of bytes.
223 Sort the list of nodes by sum of incoming and outgoing amount of packets.
225 Show amount of traffic in bytes.
227 Show amount of traffic in kilobytes.
229 Show amount of traffic in megabytes.
231 Show amount of traffic in gigabytes.
